Why Chapter I instead of Part I?

I'm here to update you on the name change. This game is planned to have 3 parts which will focus on characters named Archos, Xor'koth, and the well-known Cthulhu. This build isn't part I but instead chapter I of the first part. The chapters in this build will focus on the current demon king and Odin. After that, there are 2 more chapters that will focus on a sorceress and Xor'koth. I plan to finish this part by this year but plans change. To whoever is sticking by me for this project, thank you.
